Since b and d are perpendicular the angles they form are 90 degree angles. Also given that a and b are parallel the angles between a and d are the same as those with b and d.

SO we can say that 4x + 30 = 90
4x = 60
x = 15

Kamrynn is looking at her five quiz scores of 96 90 94 93 and 90. Determine the mean rounded to the nearest tenth median mode an

Romashka [77]

Answer:

Mean = 90, Median = 93, Mode = 90, Range = 6

Step-by-step explanation:

Mean:

96 + 90 + 94 + 93 + 90 = 463

463 ÷ 5 = 92.5

92.5 to nearest tenth = 90

Mean = 90

Median:

90, 90, 93, 94 ,96

Median = 93

Mode

96, 90, 94, 93, 90

Mode = 90

Range:

96 - 90 = 6

Range = 6

What is the value of x?

torisob [31]

Answer:

$x=45^{o}$

Step by step explanation:

We have been given that measure of angle A is fifty five degrees, the measure of angle B is eighty degrees and the measure of angle C is x.

Since we know that sum of measures of all the three angles of any triangle equals to 180 degrees.

Let us set sum of measures of all angles of our triangle equal to 180 degrees.

$A+B+C=180^{o}$

Upon substituting our given values in our equation we will get,

$55^{o}+80^{o}+x=180^{o}$

$135^{o}+x=180^{o}$

$x=180^{o}-135^{o}$

$x=45^{o}$

Therefore, the measure of angle x equals to 45 degrees.
